It has been asked on these forums before, but it hasn't been solved; Since a few weeks I suddenly can't run Jazz2. It gives an acces violation, sometimes combined with a stack overflow. No matter which version of the game I try to run or where I get it from. The editor works normally, but I can't run the game. TSF doesn't run either. I'm running Windows 7, 64 bit. But, Jazz2 has always worked. And suddenly it won't tell my why it doesn't any longer?

Going by the addresses, you're having some kind of problems with your video mode/s. The early appearance of the "VID: Closing display (DIBSection)" line in your log is also suspicious, but the really curious line is this:

WIN: Running Microsoft Windows NT Service Pack 5 version 4.0, Build 1381

You should not be seeing that if you're running JJ2 in Windows 7. I get those numbers only if I run JJ2 in compatibility mode (specifically "Windows NT 4.0 (Service Pack 5)"). JJ2 doesn't crash when I do that, but it does give you a direction to look... do you have some weird settings applied for how the program is being run? (Right click on Jazz2.exe and click "Properties") Do you maybe have an antivirus program or something similar that got updated around the time your JJ2 stopped working?

(Yes, I was running in compatibility mode. Running it with no changed properties didn't work though.) My antivirus-programm didn't have an update or anything.

It DOES run when I'm in Windows Safe Mode, I just figured out. So I probably ask a friend to check on my system, more closely than I can?

Windows Safe Mode tries to boot with only basic video support, so this problem is most likely related to your video card and/or it's driver. What kind of graphics adapter are you using? Have you tried updating it's drivers to the latest version? Any video related software installed that might come with it's own driver?

Not as far as I know -> I probably get a friend over to check on the problem, since it doesn't seem to be JJ2-related after all...

Update your graphics card drivers. If that doesn't fix it, you could try updating sound card drivers. If that still doesn't do it, you could try uninstalling your graphics card drivers, and reinstalling them.

Ah, I never actually tried (or heard of anyone who tried) JJ2 on an AMD APU. I'd like to hear what the problem was after your friend visited, assuming he/she manages to fix it!
